Custom Pre-Charged Line Sets: DIY Mini-Splits Made Easy

The market for DIY mini-split kits is growing fast, but most "DIY" units still require you to have specialized HVAC tools (like torque wrenches) and the expertise to use them. At Airspool, we wanted to go further.

Solving the DIY Hurdle

We didn't just pre-charge our refrigerant lines—we pre-installed them. With Airspool’s Quick ‘n’ Easy system, you:

  • Hand-tighten a self-sealing quick connector in seconds.
  • Avoid the need for vacuum pumps or gauges.
  • Use pre-wired communication cables (twist-to-connect).
  • Use a pre-installed power cord—just plug it into a standard wall outlet.

Custom Lengths for Custom Homes

The biggest remaining challenge was the length of the lines. A standard 15-foot line set isn't always ideal—sometimes you need more, and sometimes having 10 feet of extra coiled pipe behind your unit is unsightly.

That’s why we now offer pre-charged line sets by the foot.

  • Supplant the standard lines with a custom length tailored to your exact install.
  • We pre-install these onto your unit in our Las Vegas facility before we ship.

Tested Before It Leaves

Every Quick ‘n’ Easy unit we ship is thoroughly tested on solar, grid, and hybrid modes. By offering custom line lengths, we ensure that your installation is as clean, fast, and professional-looking as possible.
